Showing Different Response Depending on the Role and Privilege

스프링 시큐리티를 사용한다면 설정을 통해서 응답할 필드를 지정할 수 있다. 또한, 권한 별로 컨트롤러에 접근 가능여부를 설정할 수도 있다. 필드에 일일이 @JsonView 같은 애너테이션을 다는것 보다는 깔끔하게 컨트롤러를 분리하는 것이 나을것 같다. 다만, 그렇게 되면 권한 별로 분리되어야 하는 분기가 서비스, 레파지토리 계층까지 전이가 될 수 있는데, 그때마다 메서드를 분리할 것인지, 아니면 조건문으로 분기할 것인지를 또 고민해봐야 한다.
